Description
Belle has unique reach for a broad class of models that postulate the existence of dark matter particles with MeV—GeV masses. In addition, the low-background environment of electron-positron collisions and an hermetic detector make Belle II the premier experiment for studying tau-lepton physics. This talk presents recent world-leading results from Belle II searches for dark $Z’$ decays and long-lived (pseudo) scalars in $B$ decays. In addition, the world’s most precise determination of the tau lepton mass and searches for tau decays into a scalar non-SM particle and a lepton are reported.
